Bitcoin climbed more than 6% to about $77,188, extending a rally that carried it from an intraday low near $64,100 through levels above $70,000 and past $76,000, with the weekly advance approaching 25% at one stage and broader gains exceeding 20%. The move followed the US Treasury’s August 19 decision to raise the maximum size of liquidity support buybacks for 10- to 30-year nominal Treasuries from $2 billion to at least $4 billion per operation from September 9 through November 4, compressing long-term yields after the 30-year yield reached levels last seen in 2007. Lower yields reduced the opportunity cost of holding non-yielding assets such as Bitcoin, while a crypto derivatives short squeeze produced an estimated $1.1 billion to $3.5 billion in liquidations and equities rallied in a broad rotation into risk assets. Total US public debt exceeds $40 trillion, and the expanded program could add about $14 billion in incremental buyback volume over the quarter. Oil prices rose amid a US-Iran deadlock over the Strait of Hormuz, with additional support cited from institutional adoption, regulatory developments, spot buying, a weaker dollar backdrop, and positioning ahead of the Bitcoin halving. Upbit’s 24-hour volume jumped 223.8% to $1.67 billion as traders watched $80,000 resistance, support near $70,000, and key inflation and central-bank data.
